BACKGROUND AND OBJECTIVES
The human health impact of the historic and current mining and processing of non-ferrous metals in the African Copperbelt is not known. This study assessed the exposure to metals in the population of Katanga, in the south east of the Democratic Republic of Congo, using biomonitoring.
METHODS
Seventeen metals (including Cd, Co, Cu, Pb, U) and non-metals (including As) were measured by ICP-MS in urine spot samples from 351 subjects (32% women), aged 2–74yr (mean 33yr). Forty subjects (controls) lived 400km outside the mining area; 311 subjects lived in the mining area, either very close (<3km) (n=179; 6 communities) or moderately close (3–10km) (n=132; 4 communities) to mines or smelting plants.

For all metals (except Ni) urinary concentrations were significantly higher in subjects from the mining area than in control subjects. In subjects living very …
